Abstract

A reconfigurable antenna is arranged on one surface of a substrate and comprises a plurality of radiating bodies and a control circuit. The radiating bodies comprise a centre radiating body and a plurality of outer radiating bodies distributed in a regular geometrical shape with the centre radiating body as the center, and the control circuit is arranged among the radiating bodies and controls reconstruction of gains of the radiating bodies. The control circuit controls the radiating bodies so that electromagnetic radiation fields of the radiating bodies can be changed, frequency recombination and gain recombination are achieved, the antenna can be controlled through control signals to reduce frequency bands of the antenna and increase gains of certain frequency bands, and the antenna is cheap and easy to manufacture; obvious technical and cost advantages are achieved, the gains can be reconstructed when weak signals are caught, and reception capacity is enhanced.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a reconfigurable antenna and a system thereof. Background technique [0002] As a component used to transmit or receive radio waves, the antenna plays a pivotal role in the wireless communication system and is an indispensable part of the wireless communication system. With the rapid development of high-frequency satellite communication systems, radar, wireless communication systems, especially the construction of global 3G and 4G networks, the requirements for antennas are getting higher and higher. On the one hand, the antenna needs to be able to work in multiple frequency bands, have multiple working modes and have good transmission performance. On the other hand, it is necessary to reduce the weight of the antenna, reduce the volume of the antenna and reduce the cost. It is precisely because of this demand that the concept of reconfigurable antennas has been proposed a...
